Abstract
A safety module (24) is adapted to be connected to one or more smoke detectors (36) and mounted adjacent circuit breakers (12, 14) on a switch board (10). The safety module has an arm (26) that overlies the circuit breaker levers (28, 30) of the adjacent circuit breakers (12, 14). When a smoke alarm activates the arm (26) moves the circuit breaker levers (28, 30) to an open position.
Claims12
A safety module for mounting on an electrical switch board, the module including:
- a body adapted to be mounted on an elongate mounting rail of the switchboard, the elongate mounting rail having a longitudinal direction;
- at least one input for connection to at least one smoke detector, and
- a circuit breaker opener comprising at least one arm extending externally of the body and to at least one side of the body in the longitudinal direction and movable from a first position to a second position in response to said at least one signal received from at least one of said at least one smoke detector
- wherein, in use and when mounted on said mounting rail next to or adjacent to at least one first circuit breaker assembly also mounted on the mounting rail,
- the at least one first circuit breaker assembly having a housing enclosing a circuit breaker and a switch member extending out of the housing to be operated directly by a finger of a user, the switch member movable between open and closed positions to open and close the circuit breaker,
- the at least one arm extends toward said switch member of said at least one circuit breaker assembly, and
- when the switch member of said at least one circuit breaker assembly is in the closed position, the at least one arm is adjacent the switch member and movement of the at least one arm from the first position to the second position moves the switch member from the closed to open position.

A switchboard assembly including:
- a mounting rail having a longitudinal direction;
- at least one circuit breaker assembly mounted on the mounting rail, the at least one circuit breaker assembly having a housing enclosing a circuit breaker and a switch member extending out of the housing to be operated directly by a finger of a user, the switch member movable between open and closed positions to open and close the circuit breaker;
- at least one safety module mounted on the mounting rail adjacent at least one of said circuit breaker assembly, the module including:
- a body;
- at least one input for connection to at least one smoke detector,
- and
- a circuit breaker opener,
- wherein said circuit breaker opener causes the switch member of the at least one circuit breaker assembly adjacent the safety module to move from the closed position to the open position when at least one signal is received from at least one of said at least one smoke detector,
- the circuit breaker opener comprising at least one arm extending externally of the body and to one side of the body in the longitudinal direction and movable from a first position to a second position in response to said at least one signal;
- wherein, when the switch member of said at least one circuit breaker assembly is in the closed position, the at least one arm is adjacent to the switch member and movement of the at least one arm from the first position to the second position moves the switch member from the closed to open position.
