GFCI CIRCUIT BREAKERS

The PB-Series, AC Residual Current Circuit Breaker with Overcurrent Protection (RCBO), combines the ground fault protection of a GFCI with the familiar overcurrent tripping characteristics of a normal circuit breaker. It utilizes the hydraulic magnetic principle which provides precise operation and performance even when exposed to extremely hot and/or cold application environments. These precision mechanisms are temperature stable and are not adversely affected by temperature changes in their operating environment. As such, derating considerations due to temperature variations are not normally required, and heat-induced nuisance tripping is avoided.

• Overload, short circuit and ground fault protection in a single package
• Handle or rocker style actuators
• Wiping Contacts - Mechanical linkage with twostep actuation - cleans contacts, provides high, positive contact pressure & longer contact life.
• A trip-free mechanism, a safety feature which makes it impossible to manually hold the contacts closed during overload or fault conditions.
• A common trip linkage between all poles, another safety feature, ensures that an overload in one pole will trip all adjacent poles.
• Front panel mounting
• Integral push-to-test button
