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?

A

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?

A

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?

A

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?

A

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?

A

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.
