LW26GS Pad-lock Rotary Switch

About the LW26GS Pad-lock Rotary Switch

The LW26GS Pad-lock Rotary Switch is part of the ELEHPD Rotary Switch range. Classification 1) LW26GS series Pad-lock type switches have four current ratings: 20A, 25A, 32A and 63A. LW26GS-20 has two escutcheon plate types, small escutcheon plate and large escutcheon plate. Others have only large escutcheon plate. Please check out the Dimensions and installation for details. The figure 1 represents small escutcheon plate, and 2 represents large escutcheon plate. Small escutcheon plate allows two pad-locks and large escutcheon plate allows three pad-locks. 2) LW26GS series Pad-lock switches have Quick-stop and Normal if classified by operation. Normal(LW26GS□/03) has Black escutcheon plate and Black handle. Quick-stop(LW26GS□/04) has Red escutcheon plate and Red handle. ELEHPD manufactures and exports low voltage electrical products from Yueqing, Zhejiang, China, supplying distributors, panel builders, M&E contractors and OEM buyers worldwide.

Typical applications

Motor control centres and pump or fan starters
Machine building, conveyors, packaging and CNC equipment
HVAC control panels and building automation
Water treatment, irrigation and pumping stations
Panel retrofits replacing electromechanical control gear

How to specify the right Rotary Switch

Size the contact rating for the inductive load, not just the resistive current (AC-3 duty for motors)
Check the coil voltage and frequency available in the panel: 24 V DC, 110 V, 230 V or 400 V AC
Confirm the auxiliary contact count needed for the control and indication circuit
Match the enclosure rating to the environment (IP20 inside a panel, IP65 on the machine)

Specifications

Introduction
　　LW26GS series Pad-lock Rotary switches are derivatives of LW26 series rotary switches. Installed in equipment where it requires a pad-lock to lock the switch in certain position. For instance, to fix the switch in ON position, to avoid the unauthorized personnel from operating the switch.
LW26GS series Pad-lock type switch complies with the GB 14048.3 and IEC 60947.3.

Classification
1) LW26GS series Pad-lock type switches have four current ratings: 20A, 25A, 32A and 63A. LW26GS-20 has two escutcheon plate types, small escutcheon plate and large escutcheon plate. Others have only large escutcheon plate. Please check out the Dimensions and installation for details.
The figure 1 represents small escutcheon plate, and 2 represents large escutcheon plate.
Small escutcheon plate allows two pad-locks and large escutcheon plate allows three pad-locks.
2) LW26GS series Pad-lock switches have Quick-stop and Normal if classified by operation.
Normal(LW26GS□/03) has Black escutcheon plate and Black handle.
Quick-stop(LW26GS□/04) has Red escutcheon plate and Red handle.

Frequently asked questions about the LW26GS Pad-lock Rotary Switch

What is the difference between a contactor and a relay?

A contactor is built for switching power circuits repeatedly at high current, often with motor duty ratings (AC-3) and arc-suppressing chambers. A relay switches control signals at low current. In practice: contactor for the motor, relay in the control circuit that drives the contactor coil.

How do I calculate the correct contactor size for a motor?

Use the motor's full-load current, apply the AC-3 rating for the operating voltage, and allow for the number of starts per hour. As a rule of thumb, the contactor's AC-3 rating should be at least equal to the motor FLC, then step up one frame if the duty is heavy.

Do you supply the coil voltage I need?

Coil voltages are specified per order. Send the model number, coil voltage and frequency you require and we will confirm availability and lead time.

Are auxiliary contacts included?

Base models come with the standard auxiliary contact configuration for that frame. Add-on auxiliary blocks and mechanical interlocks can be quoted with the contactor.
