IC693CPU374

The IC693CPU374 circuit breakers feature thermal magnetic overcurrent protection in both C and D curves. the C curve devices are suitable for applications where medium levels of inrush current are expected, such as small transformers, lighting, pilot equipment and control circuits. the D curve devices provide false trip protection where high levels of inrush current are expected, such as motors, transformers and power supplies. The family is also suitable for reverse-feed applications. They can be DIN rail mounted and have a triple free design so that the circuit breaker will not fail by holding the handle in the ‘ON’ position. A range of field installable accessories are also available, including auxiliary and alarm switches, shunt trips, locking accessories and busbar systems.

IC693CPU374 Features:
UL 489 DIN rail mounted miniature circuit breakers rated up to 40 amps
Complete series rated at 10 kAIC @ 277/480 VAC
Suitable for protection of feeder and branch circuit equipment
Thermal magnetic overcurrent protection: two levels, C and D curves
C-curve magnetic trip point: 5 to 10 times rated current, typically used for small transformers, pilot devices, etc.
D-curve magnetic trip point: 10 to 20 times the rated current, typically used for transformers or very high inductive loads.
Anti-trip design: keeping the handle in the “ON” position will not damage the circuit breaker.
