Mozambique fire protection distribution box switch

Fire protection distribution box switches in Mozambique include MCB changeover switches, RCCBs, and input modules for fire alarm systems, available from local suppliers like Allwin Electric and ABC Extintores.

Types of Switches and Modules

1. MCB Changeover Switches These manually operated switches allow switching of electrical loads between two power supplies. They are available in 2P and 4P versions for single-phase and three-phase applications, with a center-off position for safety. MCBs provide overload and short-circuit protection for individual circuits, making them suitable for air conditioners, motors, and other critical equipment in fire protection systems . 2. Residual Current Circuit Breakers (RCCB/ELCB) RCCBs disconnect the load from the supply when residual current is detected, preventing earth leakage hazards. They are essential in fire protection distribution boxes to ensure safety from faulty wiring or poorly insulated equipment . 3. Addressable Input Modules Modules like the TCMK5211 receive signals from normally open or normally closed switches in fire linkage equipment and transmit information to the Fire Alarm Control Panel. They include features such as 24V output for external devices, main and standby power switching, and battery backup for continued operation during power outages .
