ABB RCCB, Vibration Resistant, >5000 Cycles Mechanical Lifespan - F404 Series - 2CCF544310E0400 - F404A-K40/0.03,2CC

Keen to get a handle on electrical faults? Turn to this RCCB from ABB to maintain the balance between incoming and outgoing currents in an attached circuit. If an imbalance causes current to leak to the earthing wires, this unit will quickly cut off the power supply so you won't be in for a shock. The finger-proof terminals mean you're in safe hands when setting up the breaker. As it's vibration-resistant, you can be sure it stays grounded should things get shaky.

Features & Benefits

• Can be mounted in any position for flexibility

• Mechanical endurance of >5000 operating cycles for long-term reliability

• Broad operating temperature range between -25°C and +55°C for safe use in challenging settings

Applications

• Commercial buildings

• Packaging plants

• Lighting fixtures

How can I tell if this RCCB is on or off?

Thanks to the built-in contact position display which turns green if it's on and red if it's off, you can read the operating status of this RCCB at a glance.

How do I reset this RCCB?

To reset this RCCB after a fault has been cleared, simply flip the built-in toggle switch.
