Schneider Electric Canalis KN Busbar Tap-Off Unit with Circuit Breaker, 32A, 500V, 5 Circuits KNB32CM55

Schneider Electric KNB32CM55 Busbar Tap-Off Unit is a specialized accessory for the Canalis KN busbar system, designed to provide high-performance power tapping and protection in industrial and commercial environments. Featuring a circuit breaker for integrated safety, this unit is ideal for low voltage power distribution where reliability and modular installation are priorities.

This tap-off unit is engineered with a 32A operational current capacity and supports up to 500V operating voltage, making it versatile for a wide range of electrical systems. The plug-in mounting mode helps facilitate quick installation with minimal downtime, making it suitable for both new builds and upgrades in electrical panels or distribution boards.

With its robust circuit breaker, the KNB32CM55 protects equipment against overload and short circuit faults, helping to minimize risks and downtime. Pre-wired terminal blocks allow for easy, secure connections and effective maintenance routines. The unit’s compact footprint (135 mm width, 95 mm depth, 165 mm height) allows integration where space is limited without compromising safety or functionality.

The IP55 enclosure ensures durable protection against dust and water ingress, making the tap-off unit reliable even in challenging plant or workshop environments. Supporting up to 5 circuits, it enables modular power distribution and flexible expansion for industrial automation systems, building power management, and high-performance commercial installations.

Operational reliability is further enhanced with impulse withstand voltage rated at 4.6 kV, ensuring the unit can manage transient surges and spikes that may occur in demanding electrical settings. The fixed polarity configuration and compatibility with international frequency standards (50/60 Hz) further broaden its applicability.

Typical use cases include the distribution of low voltage power within large manufacturing plants, commercial facilities, modular switchboards, and environments requiring safe, robust electrical accessories. This unit is particularly suited for installations involving modular electrical equipment, industrial automation, and environments requiring rigorous electrical standards.
