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 three pole fuse holder will accept class CC fuses. The rating of the fuse can be up to 30 Amps with a 600 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 standard fuse clips. 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
- Utilizing a precision-calibrated eutectic alloy formula, the B3.30 thermal element provides highly predictable overcurrent protection. The internal thermal mechanism melts at a precise temperature when a sustained motor overload occurs, safely releasing the starter's mechanical trip latch to disconnect power before the motor windings can experience heat damage.
- Operating on a reliable Class 20 trip curve, this thermal unit is specifically designed to tolerate the extended inrush currents of heavy-duty machinery. It provides up to 20 seconds of headroom before tripping under locked-rotor conditions, making it an excellent choice for high-inertia loads like industrial exhaust fans, heavy conveyors, and larger fluid pumps.
- Featuring a rugged, self-contained one-piece architecture, the B3.30 ensures that the critical relationship between the heater coil and the melting alloy core remains perfectly aligned. This tamper-resistant design avoids the physical distortion or field-assembly variations common with multi-part alternatives, maintaining dependable accuracy and long-term calibration consistency over years of service.
