Tmax Thermomagnetic Releases 

Thermomagnetic releases 

The Tmax T1, T2 and T3 circuit-breakers can be fitted with thermomagnetic releases and are 

used to protect alternating and direct current networks with an application range from 1A to 

250A. They allow protection against overloads with a thermal device (with adjustable threshold) 

made using the bimetal technique, and protection against short-circuit with a magnetic device 

(with fixed threshold). 

The four-pole circuit-breakers are always supplied with the neutral protected by the release 

and protection of the neutral at 100% of the phase setting for settings up to 100A. For higher 

settings, the version with protection of the neutral at 50% of the phase setting is available.

Isomax Thermomagnetic Releases 

The thermomagnetic releases which equip the SACES3 circuit-breakers have the thermal element with 

threshold adjustable from 0.7 ÷ 1 x In. The regulated current value which is obtained by using the appropriate 

selector must be intended as the rated value at 40ºC. The magnetic element has fixed trip threshold, 

with trip values which may vary according to the phase setting. 

The thermomagnetic releases which equip SACE S5 and S6 circuit-breakers have the thermal element with 

threshold adjustable from 0.7 ÷ 1 x In. The regulated current value which is obtained by using the approproate 

selector must be intended as the rated value at 40ºC. The magnetic element can be adjusted from 

5 ÷ 10 x In. The table gives the maximum magnetic trip values (10 x In) for protection of the phases (L1 - 

L2 - L3) and of the neutral.

SACE Isomax S circuit-breakers for 

motor protection (protection against short-circuit) 

Three-phase asynchronous motor starting, switching and protection are essential operations for its correct use. The traditional system 

used for this purpose has three different devices: a circuit-breaker for protection against short-circuit, a thermal relay for protection 

against overload and lack of or unbalanced phase, and a counter for the motor operations. Everything must necessarily take into account 

the problems which arise on start-up. 

In particular, these different factors must be taken into account when selecting these devices, such as: 

- the motor power 

- the starting diagram 

- the type of motor: with cage rotor or with wound rotor 

- the fault current at the point of motor installation in the network 

ABB SACEproposes a wide range of circuit-breakers, which by implementing the protection against short-circuit exclusively, are suitable 

for use inside protected starters of traditional type. 

The new SACE T2 with fixed magnetic protection is an extremely compact circuit-breaker, which stands out for its exceptional performances 

in terms of breaking capacity and limitation of the specific let-through energy. 

It can be used in a vast range of start-ups, from 0.37kW to 37kW and from 400V-50kA up to 690V-50kA. SACE S3 N/H/L 160/250 circuit 

breakers and the S3X 125/200 current-limiting circuit-breaker are fitted with a magnetic only release adjustable from 4 to 12 time the rated 

service current. They cover coordinations from 37 to 132kW and allow optimal motor protection thanks to their great flexibility due to the 

wide setting range of the magnetic threshold. 

Finally, SACES4 160/250, S5 400/630, S6 630/800, and S7 1250/1600, with different capacity levels, like the current-limiting S4X and 

S6X, can be fitted with the PR211/P (I) electronic microprocessor-based release. Above all, they are used for protection of high power 

motors and, thanks to adjustment of the protection against short-circuit from 1.5 to 12 times, allow the optimumtrip value to be selected 

for any motor type.

Current Limiting MCCBs 

Tmax T2, Isomax S3X, S4X, S6X 

Applications 

These current-limiting circuit-breakers are suitable for installation in all types of civil, industrial and service sector installations, 

as well as for electrical installations on board ships, in mines or on oil rigs, as well as, generally speaking, in any installations 

where high power generators and transformers make it possible for very high short-circuit currents of up to 200kA at 

380/415 V~, 180 kA at 440 V~ and 75 kA at 690 V~ to occur. 

The circuit-breakers can be positioned downstream of the power supply either to provide general protection (installations, 

multi-user systems and electrical lines) or for protecting electrical equipment (motors, generators, transformers and capacitors). 

They can also be fitted in systems where back-up protection is required that allows the use of circuit-breakers downstream 

which have a lower breaking capacity than the prospective short-circuit current in the point of installation. 

The breaking capacities of the SACE current-limiting circuit-breakers are higher than the best values achieved by other units 

of this type.

Emax Air Circuit Breakers 

Microprocessor-based overcurrent releases 

General specificications of the microprocessor-based releases include: 

• operation without the need for an external power supply 

• microprocessor technology (8-bit for SACE PR111 and 16-bit for SACE PR112 and PR113) 

• high precision 

• sensitivity to the true r.m.s. value of the current 

• interchangeability among all types of releases 

• setting for neutral normally 50% of setting phases, with possibility of setting it to 100% (on request 

only for circuit -breakers E1, E2, E3 standard and £4/f, E6/f full size versions). 

For the release PR113, it is also possible to select neutral protection at 150% and 200% of the rated 

current of the phases, if compatible with the setting of the current transformers. 

The main performance features of the releases are listed in the tables below.

Automatic circuit-breakers with full-size neutral conductor 

The Emax range of automatic circuit-breakers with full size neutral conductor is used in special applications 

where the presence of triple-N harmonics on individual phases may lead to a very high current 

on the neutral conductor. 

Typical applications include installations with loads having high harmonics distortions (computers and 

electronic devices in general), lighting systems with a large number of fluorescent lamps, systems with 

inverters and rectifiers, UPS, systems for adjusting the speed of electric motors. 

This range includes standard circuit-breakers with full-size neutral conductor in sizes E1, E2, E3. 

Models E4 and E6 are available in the “full size” version up to rated currents of 6300A. Models E4/f 

and E6/f are available in fixed and withdrawable four-pole versions. These models may be fitted with 

all accessories available of the Emax range; the exception, on the E6/f model, are the mechanical 

interlocks made using flexible wires and 15 external auxiliary contacts, which are therefore incompatible. 

All the models may be fitted with all available version of electronic protection relays, in the standard 

version.

Switch-disconnectors 

The switch-disconnectors are derived from the corresponding automatic circuit-breakers, of which 

they maintain the overall dimensions and the possibility of mounting accessories. 

This version differs from the automatic circuit-breakers only in the absence of overcurrent releases. 

The circuit-breaker is available in both fixed and withdrawable versions, three-pole and four-pole. The 

switch-disconnectors, identified by the label “/MS”, may be used according to the category of use AC- 

23A (switching motor loads or other highly inductive loads) in accordance with the standard IEC 

60947-3. The electrical specifications of the switch-disconnectors are listed below.
