Junction box PUH-3P-M20 — No name, PUH-3P-M20 connection enclosure with M20 gland entry

PUH-3P-M20 junction box by No name is a compact connection enclosure designed to protect electrical cable terminations and wire splices in indoor installations. The enclosure provides a single cable entry compatible with M20 cable glands or conduit fittings, offering a small footprint for mounting inside control panels, lighting circuits, service rooms, and general-purpose wiring applications where a neat, protected junction point is required.

Advantages

The PUH-3P-M20 offers a compact design that simplifies installation in confined spaces while providing mechanical protection for connections. Its M20-compatible entry allows flexible use of standard cable glands and conduit, enabling secure cable strain relief and environmental separation. Constructed for routine indoor electrical environments, the enclosure helps organize wiring and reduce exposure of splices to accidental contact.

Suitable for

• Indoor lighting circuits and ceiling or wall-mounted fixtures
• Control panel internal wiring and junction points
• Small machinery and equipment power terminations
• General-purpose household or commercial wiring junctions

Key specifications

• Compact rectangular enclosure sized for small cable terminations
• Single M20-compatible cable entry for glands or conduit
• Provision for secure mounting inside cabinets or on flat surfaces
• Internal space for splicing and termination of up to three conductors per phase depending on conductor size
• Suitable for indoor use and standard ambient electrical environments

How to use

Mount the junction box on a clean, flat surface or inside a panel using suitable screws through the provided mounting points. Fit an appropriate M20 cable gland or conduit adapter into the cable entry and secure it according to the gland manufacturer's instructions. Route the incoming and outgoing cables through the gland, strip conductor insulation to the required length, and make connections using appropriate connectors or terminal blocks. Ensure all connections are tightened to the correct torque and that the gland provides adequate strain relief. After wiring, close and secure the enclosure cover to maintain protection of the terminations.

Usage recommendations

Use the enclosure only in dry indoor environments and select cable glands rated for the cable diameter and environmental conditions. Verify conductor sizes and connector ratings before making splices, and follow local electrical codes for mounting and earthing. For installations with higher ingress protection or outdoor exposure, choose a suitably rated enclosure and accessories.
