This surge protector from Eaton makes shielding against electrical spikes and transients a piece of cake. As a circuit-breaking device also known as a shunt trip, it trips your circuit remotely during a surge to prevent harm to users or damage to connected equipment. This three-phase unit is designed for use in control panels and has a maximum voltage of 415V AC/230V DC, so it's a practical pick for industrial settings. You get the benefit of reduced wiring times thanks to the handy twin-purpose terminals that open above and below so you can install bus duct and cables at the same time.

• Versatile device can be used with a standard auxiliary switch or mounted onto an existing MCB for extra protection
• Red/green indicator keeps you up to speed on switch position
• Adaptable unit works with AC or DC voltages for application versatility
• IP40 rating means it resists tools or wires with a diameter of over 2.5mm
• Operating temperature from -5°C to +40°C, so it suits harsh settings

You can mount this surge protector directly onto a standard 35mm DIN rail or attach it to an existing MCB or auxiliary switch that needs more protection.
