Contactum MCB ( Type C )
16 Amp - Single Pole
General Distribution Board use
Type C devices are capable of supplying the majority of inductive and capacitive loads such as motors, transformers and tungsten or fluorescent lighting.
Surges on energisation, for example with discharge lighting, may well reach 25 times the rated current of the device, but only for very short duration. Type B devices will often be adequate, but for more specialised circuits, a Type C may be required. The lighting fitting manufacturers recommendations should be observed.
Contactum MCB's detect overcurrents due to both overload and fault currents.
The MCB will operate and interrupt the supply to prevent damage to the installation.
Contactum Industrial Range MCBs have a short circuit breaking capacity of 10,000A (M10).
- The current carrying capacity of the cable should always exceed the current rating of the MCB to prevent damage.
The operating dolly may be locked in either the ON or OFF position without affecting the ability of the trip mechanism to operate.
- When the green flag below the dolly is visible, then a contact gap of 4 mm has been achieved. Contactum MCBs may therefore be used as single pole isolating switches where appropriate.
