摘要： A service entrance barrier for a load center that includes a housing and a service entrance having at least one branch fed main breaker electrically connected to branch feed lines. The service entrance barrier is securable to the load center housing to prevent human contact with electrically energized parts located in the service entrance of the load center. The service entrance barrier includes a main body portion, at least one mounting leg extending from the main body portion, a protection tab extending from said main body portion, and a non-conductive sleeve encompassing the protection tab.

摘要： A circuit breaker configured to be remotely operated is disclosed. The circuit breaker includes a set of main contacts configured to connect between an electrical source and an electrical load, an operating mechanism in operable communication to open and close the main contacts, and a remotely operable drive system configured to open and close the main contacts separate from actuation of the operating mechanism. The drive system includes a motor responsive to first and second control signals, a primary drive responsive to the motor, and an opening spring responsive to the primary drive, the main contacts being responsive to the opening spring. In response to the first control signal, the primary drive moves to charge the opening spring, and in response to the second control signal and the main contacts being closed, the primary drive moves to allow the opening spring to discharge thereby resulting in the main contacts opening independent of the motor.

摘要： A multi-pole mounting base for interfacing a circuit breaker and/or circuit interrupter with an electrical panel is disclosed. The electrical panel has an interior configured to receive remote operated circuit breakers (ROCBs) in signal communication with a communication board internal to the electrical panel, non-ROCBs, and ground fault circuit interrupters (GFCls). The mounting base includes a unitary support platform assemblable to the interior of the electrical panel and having first mounting regions with common structure configured to receive any one of the ROCBs, the non-ROCBs, and the GFCls. The support platform also has second mounting regions configured to receive the communication board. The support platform is configured to assemble adjacent to another support platform in the electrical panel.

摘要： An integrated protection unit is an electronic trip circuit breaker which includes basic overcurrent protection facility along with selective electrical accessories. A molded plastic accessory access cover secured to the integrated protection unit cover protects the accessory components contained within the integrated protection unit cover from the environment. A combined overcurrent trip actuator and multiple accessory unit can be field-installed within the integrated protection unit. The combined actuator-accessory unit includes electronic control circuitry for the accessories along with mechanical trip and reset interface components. Additionally, a bell alarm signal unit can be incorporated within the trip actuator and multiple accessory unit enclosure.

摘要： An integrated protection unit is a circuit breaker which includes basic overcurrent protection facility along with selective electrical accessories. A molded plastic accessory access cover secured to the integrated protection unit cover protects the accessory components contained within the circuit breaker cover from the environment. An auxiliary switch unit is one such accessory component which can be field-installed without affecting the integrity of the circuit breaker and which is connected to a remote indicator connected by external wire conductors to signal the "ON" or "OFF" condition of the circuit breaker contacts. The auxiliary switch unit enclosure is specially shaped to protect the auxiliary switch from damage due to excess tension on the external wire conductors.

摘要： An interchangeable operating mechanism assembly for molded case circuit breakers having a detachable movable contact arm and trip unit assembly allows the same mechanism assembly to be employed across a wide range of breaker ratings. A snap-on common trip bar attachment further allows multiple-pole facility off the common interrupter mechanism assembly. The mechanism assembly is designed to maintain the operating handle in the "on" position upon the occurrence of a welded contact and prevents the mechanism from being reset.
