ESP 5A/BX & 16A/BX Series Application Use these protectors on low current mains power supplies, e.g. CCTV cameras, alarm panels and telemetry equipment. Installation Connect in-line with the power supply usually either within the equipment panel (or for CCTV cameras, in an enclosure close by), or on the fused connection that supplies equipment. Earth DIRTY CLEAN Combined Type 2 and 3 tested protector (to BS EN 61643) for use To on low current (up to 5 or 16 A) single phase systems to protect From line equipment connected electronic equipment from transient overvoltages on Connect in-line on supplies fused up to 5 A the mains supply, e.g. fire/intruder alarm panels. Protectors with (ESP 120-5A, ESP 240-5A or ESP 277-5A) or 16 A (ESP 120-16A, ESP 240-16A or /BX suffix come ready-boxed, to IP66, for use in dirty or damp ESP 277-16A).
