Square D NSYMM43 Mounting Plate for Elec Boxes Steel 400x300mm

Description

Product Overview

The Square D NSYMM43 mounting plate is engineered by Schneider Electric to serve as a versatile, high‑strength platform for a wide range of electrical enclosures. Constructed from cold‑rolled carbon steel with a galvanized finish, the plate resists corrosion and provides a durable mounting surface that can sustain loads up to 60 kg. Its dimensions of 400 mm height by 300 mm width make it an ideal match for standard Spacial CRN, S3D, S3X, and PLM boxes, while the unfinished surface allows for optional coating or painting to meet specific project requirements. The plate includes pre‑drilled M8 screw holes for quick, secure attachment to backstuds or for step‑slide mounting, simplifying the installation process for electricians and contractors.

Usage

This mounting plate excels in both commercial and residential applications where space efficiency and load‑bearing capacity are critical. It is commonly used in data centers, industrial control panels, and building automation systems to secure transformers, circuit breakers, and distribution blocks within confined enclosures. The plate’s flat, plain design maximizes interior volume, allowing more equipment to be installed without compromising safety clearances. Its screw‑in installation method enables rapid deployment in new builds and easy retrofitting during upgrades or maintenance cycles. The plate is also suitable for outdoor-rated enclosures when paired with appropriate weather‑sealed hardware, making it a reliable choice for utility pole installations and remote monitoring stations.

FAQ

What size enclosures is the NSYMM43 plate compatible with?

The plate is designed for enclosures measuring 400 mm in height and 300 mm in width, which includes Spacial CRN, S3D, S3X, and PLM series boxes.

Can the mounting plate be painted or coated?

Yes, the unfinished surface allows users to apply paint, powder coating, or other protective finishes to match project specifications or aesthetic requirements.

What is the maximum load the plate can support?

The galvanized steel plate is rated for a permissible load of up to 60 kg, making it suitable for most transformers, breakers, and distribution equipment.

Is the plate suitable for outdoor or wet‑location installations?

When used with appropriate weather‑sealed hardware and installed in a properly rated enclosure, the plate’s galvanized finish provides corrosion resistance for outdoor applications.

How does the step‑slide mounting option work?

The step‑slide option allows the plate to be positioned on a raised ledge within the enclosure, providing additional clearance for wiring and improving heat dissipation while still using the same M8 screw points for secure attachment.
