ALPHA SIMBOX Small Distribution Boards
SIMBOX WP
Introduction
■ Overview
• Small distribution boards for modular installation devices with
device mounting depths up to 70 mm
• Modular width 1 MW r 18 mm
■ Benefits
• The wiring space behind the standard mounting rail is 15 mm
and 48 mm, ensuring fast and easy wiring.
• The extremely robust transparent door can also be equipped
with a lock, which can be ordered from the range of accessories.
The door can be hinged on the right or left without tools;
its opening angle is 180°.
• The withdrawable equipment rack ensures easy and fast assembly.
The generous wiring space and clearly arranged
modular design reduce assembly times by approx. 20 %.
• The plastic materials used can be recycled.
■ Application
Due to the high degree of protection IP65, these small distribution
boards can withstand harsh ambient conditions in both indoor
and outdoor areas.
Their resistance to dust and splashing water makes them ideal
for use in a range of different application areas, such as car
washes, farms, joiners' workshops, etc.
Special applications
Due to their large temperature operating range (-25 °C to
+60 °C), UV radiation resistance and resistance to dust and
splashing water, this distribution board range is especially suitable
for harsh ambient conditions.
■ Design
Equipment
The distribution boards can be equipped with modular installation
devices, such as MCBs and RCCBs, with 63 A and up to a
mounting depth of 70 mm, by snapping them onto the standard
mounting rails 35 mm x 7.5 mm to EN 60715.
The small distribution boards can be equipped with devices of
12 to 18 modular widths as required.
