Developed in South Africa, the Coalbuster Section switch with microprocessor control has been designed to meet worldwide mining standards. The complete switch is protected from short circuit by extremely fast acting electronics and a circuit breaker located in the top busbar chamber. The PEFLO controlled relay and microLOAD overload relay provide a user friendly, reliable, simple system combined with superior operating control parameters. Microprocessor controled relays have reduced the internal panel wiring and component count.Different outlets can be interlocked and sequence started for typical mining applications.
