Advanced protector for DC supplies and DC power distribution systems.
Protection for 12, 24, 36 and 48V DC systems.
For low current applications, see the H series (4A) protectors here, E series (1.25 A) here or D series (300mA) here.
Application
Use on DC power distribution systems to protect connected electronic
equipment from transient over voltages on the DC supply, eg DC fed
communications or control equipment.
ESP DC Brochure
Installation
Install in parallel, within the power distribution board or directly on the supply feeding the equipment.
At distribution boards, the protector can be installed either on the
load side of the incoming isolator, or on the closest outgoing way to
the incoming supply. Connect, with very short connecting leads, to
positive, negative and earth. On supplies over 100 amps, phase/live
connecting leads should be fused with either 63 or 100 amp high rupture
capacity (HRC) fuses, a switch fuse, MCCB or type"C"MCB.
Suitable accessories
If the protector cannot be incorporated within the panel, use the WBX 3 enclosure.
