ESP M1 Series Electronic Systems Protection

240m1cs F2_0708
415 m1cs_0708

• Very low let-through voltage (enhanced protection to BS EN 62305) between all sets of conductors (phase to neutral, phase to earth, neutral to earth – Full Mode protection)
• Full mode design capable of handling partial lighting currents as well as allowing continual operation of protected equipment
• Repeated protection in lightning intense environments
• Innovative multiple thermal disconnect technology for safe disconnection from faulty or abnormal supplies (without compromising protective performance)
• Three way visual indication of protection status and advanced pre-failure warning so you need to be unprotected
• Remote indication facility allows pre-failure warning to be linked to a building management system, buzzer or light
• Changeover active volt-free contact enables the protector to be used to warn of phase loss(i.e. power failure, blown fuses etc)
• Flashing warning of potentially fatal neutral to earth supply faults (due to incorrect earthing, wiring errors or unbalanced conditions)
• Robust steel housing
• Base provides ultra-low inductance earth bond to metal panels
• Compact size for installation in the power distribution board
• ESP 120 M1 and ESP 240 M1 have Network Rail Approval PA05/02700 and PA05/01832 respectively. NRS PADS reference 086/000556 (ESP 120 M1) and 086/047149 (ESP 240 M1)
