The MEGA® Fuse is designed for high current circuit protection up to 250 amperes. with "Diffusion Pill Technology". The MEGA® Fuse also provides time delay characteristics. Designed and patented by Littelfuse, the MEGA® Fuse is ideal for battery and alternator protection application and other heavy gauge cables requiring ultra-high current protection.

TR Series dual pole 500A Master Disconnect Switch cuts all battery power from vehicle electrical systems with applications needing switching of two circuits, or both positive and negative. Ingress protection to IP67 and IP69K means that the switch can be mounted in exposed locations on the vehicle. Drop-in replacement for competitive Master Disconnect Switches, with higher vibration and shock capabilities. 500A continuous current rating for each of the two circuits (using 2 x 4/0 input and 2 x 4/0 output cables). Can be used to switch two vehicle voltage circuits simultaneously (24V and 12V). Disconnect a battery or multiple batteries, in either the positive or the negative line. Direct lockout/tagout capability in On or Off position, with padlock or hasp. Specifications: Max operating voltage: 48V DC; Max continuous current: 500A per circuit, with 2 x 4/0 input and 2 x 4/0 output cables; 350A per circuit, with 1 x 4/0 input and 1 x 4/0 output cables; Cranking rating (30sec): 2250A per circuit, with 2 x 4/0 input and 2 x 4/0 output cables; 1750A per circuit, with 1 x 4/0 input and 1 x 4/0 output cables; Inrush rating (1 sec): 3000A per circuit with 2 x 4/0 + 1 x 2 AWG; Terminal stud size: M12 x 25mm; Temperature range: -50° to 85°C, DC-Rated to 105°C; Humidity: 0 - 95% RH; Shock: 30 G; Vibration: 8 G; Ingress rating: IP67 & IP69K.

5x20mm meduim- acting glass body fuse designed to UL specification. Features: Designed to UL/CSA/ANCE 248 Standard; Available in cartridge and axial lead format; RoHS compliant and lead-free.

POWR-BLOK covers provide protection against accidental shorting between poles caused by loose wires, tools, or other conductive material. They also protect personnel from accidentally contacting energized connectors. To order protective covers, match the number of poles for the block to the cover.

Operates on AC ungrounded systems. The EL3100 is a self-powered ground-fault and phase voltage indication system for 3-phase systems. The EL3100 meets the National Electrical Code (NEC, Article 250.21(B)) and the Canadian Electrical Code (CEC) requirements for ground detectors for ungrounded alternating-current systems. Voltage connections are provided on the EL3100 for 208, 240, 480, and 600-V systems. Three green LED’s on the EL3100 indicate the presence of phase-to-ground voltage and one red LED indicates a ground fault. The EL3100 can operate stand-alone or with up to five remote LED indicators. A solid-state relay output provides indication of a ground fault. The output relay is closed when the 3-phase neutral voltage shifts as the result of ground leakage.
