WJ Furse, ESP 240 Surge Protection Device 280 V Maximum Voltage Rating 10kA Maximum Surge Current Low Current Mains

Over Voltage protectors for low current mains power supplies to protect electronic equipment e.g. CCTV cameras, alarm panels and telemetry equipment.

Very low let-through voltage between all lines (L-E, L-N, N-E)
Sturdy housing with M6 earth stud
Removable DIN rail foot for easy installation (unboxed versions). Can also be flat-mounted.
IP66 rated boxed version (/BX parts)
Colour-coded terminals

Tough polycarbonate enclosures

WBX enclosures for ESP protectors provide added protection in damp and dirty environments. Ideal for use when the protectors cannot be installed within an existing equipment panel or enclosure.

Network Rail approval (ESP 240-5A/BX) – PA05/02896. NRS PADS ref: 087/037285

This surge protection device is crucial for protecting electrical systems against voltage spikes and transients. Designed for low current mains applications, it mitigates risks associated with surges while ensuring consistent performance. With a maximum voltage rating of 280V and impressive surge handling capabilities, this device is an important component for enhancing electrical safety across various environments.

• Withstands maximum surge currents of 10kA
• Compact design optimises space in electrical installations
• Complies with industrial surge protection standards

• Used in commercial electrical installations
• Protects sensitive electronic equipment
• Applicable for residential electrical safety devices
• Ideal for machinery and equipment needing surge protection

The device mounts directly onto a DIN rail for a secure fit. Ensure the electrical supply is disconnected before proceeding, and connect the input and output terminals as per your system’s specifications.

It is designed to function in temperatures ranging from -40°C to +80°C, making it suitable for environments with challenging conditions.

While it is straightforward to install on a DIN rail, it is advisable to consult a qualified electrician to ensure proper setup and compliance with local electrical regulations.

Transient Voltage Suppressors (Modules,Industrial)

Voltage surges, often referred to as spikes or transient overvoltages are typically caused by switching of fluorescent lights, fuses blowing or nearby lightning activity. The worst voltage surges are usually caused by lightning activity and can reach up to 6000V, with current surges of up to 3000A. The maximum size of the voltage and current surges depends on the location within the buildings wiring system. BS6651:1999 Annex C which was replaced in August 2008 by BS EN 62305-4:2006 is complemented by BS EN 61643-11/12 and covers location categories and provides guidance on protection of electronic equipment. For mains power systems, Types I, II and III are used. Surge protection devices not designed to fit into these categories may only provide limited protection and the equipment they protect may suffer damage.
