ED125 ED250 ED300 125 250 300 Amp 12V 24V 48V 125A 250A 300A SPST Manual DC Emergency Stop Disconnect Switch for Forklift Pallet Truck Golf Cart

Application:

ED125/ED250/ED300 range of switches have been designed to provide a rapid means of disconnecting batteries or other DC power supplies in the event of serious electrical faults. Whilst the switches are primarily intended for use with battery powered vehicles. They are also suitable for use with static power systems. All type are capable of safely rupturing full load battery currents in the event of an emergency.

Technical FAQ & Selection Guide

💡 Frequently Asked Technical Questions & Selection Guide

Pure engineering specifications, tripping curve parameters, and electrical selection guidance for panel builders and system designers.

Voltage & Load Sizing

How to verify rated operational voltage, frequency, and load duty cycle?

Verify that the nominal line voltage (AC 230V single-phase or 400V/415V/690V three-phase at 50/60Hz, or DC voltage ratings) falls within the continuous maximum operating limits of the device. Check duty cycle ratings (continuous vs intermittent duty) to ensure thermal stability under full load.

Protection & Environment

What ingress protection (IP Rating) and environmental enclosures are recommended?

For clean indoor electrical rooms, standard IP20 modular DIN-rail housings are recommended. For outdoor, industrial washdown, or dusty environments, mount components inside weatherproof enclosures rated IP65/IP66 with UV-resistant polycarbonate or powder-coated steel enclosures equipped with compression cable glands.

Selectivity & Grading

How to ensure upstream and downstream coordination in power distribution boards?

Ensure proper discrimination by grading current thresholds and tripping time delays: upstream devices should have higher current ratings and intentional short-time delays (Class S), allowing downstream branch MCBs to clear localized faults without blacking out the entire facility.

Installation & Mounting

What mounting rails, busbars, and spatial clearances are required?

Components mount on standard symmetrical 35mm DIN rail (EN 60715 / TH35-7.5) or backplate screw fixings. Maintain recommended top/bottom ventilation gaps (typically 30–50mm) to ensure unrestricted air convection, and use standard pin/fork comb busbars to minimize contact resistance and wiring errors.

Conductor & Torque Sizing

What conductor sizes and terminal tightening torques should be applied?

Select copper or aluminum conductor cross-sections complying with IEC 60364-5-52 current-carrying capacity tables based on continuous load. Always use a calibrated torque screwdriver or torque wrench to tighten terminal screws to the manufacturer-specified torque to prevent hot-spot degradation and loose connections.
