Description

LW26 Rotary Switch 10A 20A 25A 32A 63A 125A 160A substitute for LW2 LW5 LW6 LW8 LW12 LW15 HZ5 HZ10 HZ12 Cam Changeover Switch

Introduction:

The LW26 sereies rotary switch mainly applies to 440V and below,AC 50Hz or 240V and below DC circuits.For breaking and closing,change-over of circuits under unfrequenly manual operation.And the typical application are:control switch of 3 phase motors,control switch gear,control switch of instruments,and change-over switch of machinery and welding machine.
The series comply with the IEC 60947-3,IEC 60947-5-1.
The LW26 series have 7 current ratings:10A,20A,25A,32A,63A,125A and 160A.
The LW26 series rotary switch were designed for multiple functions,wide variety of applications.
The LW26-10,LW26-20,LW26-25,and LW26-32F have finger protection terminals.
LW26 series rotary switch are an excellent substitute for LW2,LW5,LW6,LW8,LW12,LW15,HZ5, HZ10,and HZ12.
The LW26 series rotary switch has two derivatives,LW26GS Pad-lock and LW26S lock.
Both of them are applicable in circuits when an physical control is required.
We can equip protective box for 20A,25A,32A and 63A.

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.
