Power range miniature circuit breakers
The Clipsal Power Range has arrived, and with it comes everything you need for your residential, commercial or industrial switchboard requirements.
Included are MCBs, RCDs, MCB/RCD combinations, isolating switches, changeover switches and busbar systems.
A huge variety of accessories are also available to complement the range, including auxiliary contacts, shunt trip and voltage protection devices, push-buttons, audio and visual signalling devices, timers, relays, contactors, counters and transformers.
Housing for all mainstream devices is of sturdy, self-extinguishing material in a neutral grey colour to suit most switchboard designs.
Each Miniature Circuit Breaker has colour coded toggles for easy and safe amperage rating identification, ‘lift-up’ terminals with combination head screws and a status indicator window with a red/green colour coded flag that is coupled to the contact mechanism. Additional safety is provided with ‘ON’ and ‘OFF’ marking in contrasting colours on toggle mechanisms.
All devices are for 35mm DIN Rail mounting with a two position DIN clip of heavy duty moulded material. Miniature Circuit Breakers (MCBs) are constructed with provisions for quick, easy and safe field application of auxiliary contacts and shunt trip release mechanisms. Mechanism locking and sealing wire facilities are also provided where required.
The Power Range MCB is an all new high performance current limiting device with the ability to disconnect short circuits up to 10kA (1 module) and 25kA (1 1/2 module).
Clipsal Power Range MCBs include two types of operation:
|
|
1
|
Thermal for normal overload |
2
|
Magnetic for short circuit protection |
Thermal operation occurs when the bi-metal strip(1), is heated by the overload current and deflected. This trips the tripping lever (2) which, with its spring action (3), causes the contacts (4) to open.
Magnetic tripping is achieved by utilising the solenoid (5) which causes the armature (6) in conjunction with the mechanical action of the spring (3) to open the MCB’s contacts.
Note: The splitter plates (7) break up the ionised gas as the switch mechanism opens, extinguishing the arc.

Top or bottom connection
Clipsal MCBs allow line or load cables to be connected at either top or bottom for greater installation flexibility.
Free tripping mechanism
The 4 Series Power Range MCB mechanism is free tripping and cannot be held in the on position against a fault.
If the switch is held in the on position, the MCB will still operate.
Four main groups of Power Range MCBs are available to suit most applications
These MCBs will cater to almost all applications, with models available from 1 to 125 amps.
Amperage ratings on all models are easily determined with the aid of colour coded toggles
