ABB RCBO, 3W Power Loss, 4kV Rated Impulse Withstand Voltage - DSE201 M Series - 2CSR275151R1205 DSE201 M B20 A30 - N Blue

Don't let residual currents and overloads trip up productivity – protect your circuits with this RCBO from ABB. In the event of a fault, it steps in to cut power to your equipment instantly, saving it from damage. The unit's thermoplastic housing can resist impact, so it's tough enough to brave the rigours of tough industrial environments. Thanks to its narrow 18mm width, it sits neatly in setups with limited space. After it's done its job, a toggle switch makes it a doddle to reset.

Features & Benefits

• Mechanical endurance of 20,000 operating cycles for long-term performance

• 4kV rated impulse withstand voltage to handle sudden power surges without suffering damage

• 20A current rating makes it suitable for high-current-consuming applications

• Wide operating temperature range between -25°C and +55°C for use in demanding conditions

Applications

• Residential wiring

• Industrial lighting systems

• Process and packaging equipment

Is this RCBO finger-safe?

Yes, this unit's terminals have an IP20 rating, which means that it's protected against anything larger than 12mm, like your fingers. This prevents contact with live parts and enhances safety.
