Schneider Electric Multi 9 C60BP Circuit Breaker - 3P, 6A, Curve C

'3P' stands for 3-pole, indicating that the breaker can simultaneously switch and protect three separate electrical conductors. This is commonly used for three-phase power or multiple single-phase circuits.

A Type C tripping characteristic is designed to handle moderate inrush currents, typically 5 to 10 times the nominal current, for a short duration. This makes it suitable for inductive loads like motors and transformers that experience higher currents upon startup.

The breaking capacity (Icu) is 15 kA at 440V AC. This means it can safely interrupt a short-circuit fault current of up to 15,000 Amperes at that voltage without being destroyed.

While it provides protection, this model is specifically designed for control panel builders and OEMs. Residential applications might typically use different types of breakers optimized for those specific codes and requirements. Always consult local electrical codes and a qualified electrician.

You need to calculate the total continuous current draw of the equipment or circuits the breaker will protect. Ensure this total does not exceed 80% of the breaker's 6A rating for continuous loads (NEC guidelines). Consult an electrical professional if unsure.

The operating temperature range for this circuit breaker is -30°C to 70°C.

This 3-pole breaker occupies 6 modules of 9mm width each on a standard 35mm DIN rail. This means it takes up a total width equivalent to 6 x 9mm = 54mm.

This typically indicates a short circuit. Disconnect all loads and re-energize with no load connected. If it still trips, inspect wiring for faults. If it holds with no load, the issue is with the connected load.

This suggests an overload condition. Verify that the connected load does not exceed the breaker's 6A rating. Check for excessive inrush current if the load involves motors or transformers.

Ensure the fault condition that caused the trip has been cleared. If the breaker is mechanically damaged, it may need replacement.

Slight warmth can be normal due to current flow, but excessive heat indicates a potential issue. Check for loose connections or a load exceeding the breaker's continuous capacity. Ensure adequate ventilation around the breaker.
