Description
Linergy NEMA fuse holders are panel mount fuse holders that will accept class H, R, CC, M, and J fuses up to 200 Amps. This two pole fuse holder will accept class R fuses. The rating of the fuse can be up to 30 Amps with a 250 V maximum rating. The pressure wire connectors will accept 14 to 10 AWG (2.5 to 4 mm2) solid or stranded copper wire. Fuse clips are made of a copper alloy that is tin plated. The fuse clips are reinforced for a better connection. The fuse holder base is made of high impact thermoplastic. AIC Rating in accordance with UL512 is 200,000 Amp. This fuse holder is UL listed and CSA certified.
Features
- The Schneider Electric B19.5 thermal unit features a standard plug-in design engineered specifically for seamless installation in Square D Type S and Type B thermal overload relays.
- Utilizing a precision-engineered eutectic melting alloy sensing mechanism, this thermal unit monitors the exact heat signature generated by full-load currents. If a sustained overload occurs, the thermal alloy melts at a precise temperature threshold, instantly tripping the relay and breaking the circuit to protect your motor windings from costly phase or operational burnout.
- Certified as a Class 20 standard trip thermal unit, the B19.5 is rated to safely interrupt the circuit within 20 seconds or less when current spikes to six times the motor's full-load rating. This deliberate delay prevents nuisance tripping during normal, high-torque motor startups while ensuring definitive, automated protection during prolonged, dangerous overcurrent conditions.
