M56 Series Metal Switches technical data

Product catalog summary

Introduction

The M56 Series by Gerard Industries Pty Ltd comprises heavy-duty metal switches and accessories designed for industrial and commercial use. Constructed from cast aluminium, these products offer enhanced strength and durability while maintaining compatibility with the existing plastic 56 Series range.

Modular Design and Applications

The series features a modular design enabling interchangeability between metal and plastic components. It is tailored for harsh industrial environments such as mining, rail, workshops, and process handling, where impact resistance and earthing continuity are essential. The M56 Series supports installations using metal conduit and steel wire armoured cables.

Temperature Range

Junction Boxes: -35°C to +95°C
Standard Switches: -35°C to +40°C (with potential for higher ratings via derating)

Product Features

Material and Coating: Diecast aluminium with a two-part polyurethane coating for corrosion resistance and lightweight strength.
Mounting: External stainless steel mounting feet secured with No. 10 gauge screws, ensuring easy installation and maintaining IP66 rating.
Sealing and Protection: All products comply with IP66 standards (AS1939-1991), providing robust protection against dust and water ingress.
Padlocking: Switches can be locked in the off position using a standard 6.4mm shank padlock.
Identification: Clear labelling of switch positions, ratings, and product identification for user convenience.
Metal Components: All external hardware is stainless steel to resist corrosion.

Surface Switches and Push-Buttons

The surface switches range from 10A at 250V to 63A at 500V, featuring positive rotary action with clear ON/OFF markings and padlock provisions. Earth and neutral connectors support up to 3 x 6 sq. mm cables. Push-buttons have rugged mushroom heads with twist reset and red coloring, compatible with Clipsal 6 Series metal push-buttons.

Mounting Enclosures, Junction Boxes, and Accessories

Junction Boxes (M56JB1): Equipped with 2 x 25mm and 1 x 32mm conduit entries, earth and neutral connectors, and sealing gaskets. Fully interchangeable with plastic 56 Series enclosures.
Mounting Enclosures (Back Boxes): Designed for heavy industrial use and compatible with plastic 56 Series components to maintain earthing continuity.
Lids (M56L1): Include sealing gaskets and fixing screws.
Metal Conduit Plugs: Chromated aluminium plugs available in M20, M25, M32, and M40 sizes for sealing unused conduit entries.

Technical Specifications and Ratings

The catalogue details switch models with parameters including conventional enclosed thermal current (Ithe), insulation voltage (Ui), operational voltage (Ue), operational current (Ie), utilization categories (AC21, AC22, AC23), cable terminal sizes, IP ratings, and dimensions. All switches maintain an IP66 rating, ensuring high ingress protection.

Technical Drawings

Technical drawings provide front and side views, conduit entry points, mounting dimensions, and internal switch mechanisms. They clarify conductor termination types (pressure plate or plain screw), wiring methods (backwired or sidewired), and padlock hole dimensions.

International Protection Ratings

The M56 Series complies with IP66 protection standards per AS1939-1991, ensuring resistance to dust and powerful water jets, suitable for demanding industrial environments.
