- Contactum Domestic MCBs have a short circuit breaking capacity of 6000A (M6).
- 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.
