SINGLE POLE 45A CONNECTOR RED

SINGLE POLE 45A CONNECTOR RED

The SINGLE POLE 45A CONNECTOR RED is a compact high-current quick-disconnect connector for battery and DC power wiring. It is rated in the 45A current class and uses a red housing, commonly used to identify the positive side of a DC circuit. A single-pole format lets designers build modular power connections one conductor at a time, which is useful in battery packs, charging harnesses, DC distribution, industrial equipment and service fixtures where quick connection and disconnection are required.

Unlike a fixed cable lug, a plug-style connector is designed for repeated mating. That makes contact selection, crimp quality and housing condition important to long-term performance. The connector should be used with the correct contact family and conductor size for the actual current, and the two halves must be fully seated during operation. A 45A label does not override the thermal limits of the wire, terminal crimp, mating contact or surrounding enclosure.

The product is identified as a single-pole 45A connector with a red insulated housing and copper conductive contacts. Current market references for this connector family specify up to 600V, but final system voltage must remain within the verified rating of the exact supplied contact and housing combination. The red color is a practical polarity cue and is normally associated with the positive or live DC conductor; installers should still verify polarity electrically rather than relying only on color.

Low contact resistance is essential because resistance at a detachable connector produces heat under load. Contacts should be crimped using the correct tool and die, with no loose strands or under-crimped conductor. The mating faces should stay clean and undamaged. If the connector is used in a vibrating vehicle or mobile system, cable support and strain relief should prevent the wire from loading the contact interface.

Select the connector by current requirement, system voltage, wire cross-section, contact size, housing color and mating family. Similar single-pole housings are available in multiple current classes, and parts that look alike are not always mechanically or electrically interchangeable. For repair work, compare the existing housing and contact dimensions before ordering. Where several single-pole connectors are grouped together, maintain clear polarity identification and mechanical arrangement so positive and negative circuits cannot be accidentally cross-connected.

Applications

• EV, e-rickshaw, e-bike and battery-service harness connections.

• Solar, UPS and inverter battery wiring requiring a detachable DC connector.

• Battery chargers, test benches and workshop fixtures.

• Industrial DC power, robotics and portable power equipment.

• Custom battery packs and modular power-distribution assemblies.

Installation Guide

Disconnect all power before crimping or assembling the connector. Strip the conductor only to the required length, use the correct contact and crimp tool, and inspect the finished crimp for full conductor capture. Insert the contact until it is positively retained in the housing. Confirm polarity with a meter before mating to the system. During commissioning, apply load gradually and check for abnormal heating. Replace the connector if the housing, contact or cable entry shows discoloration, melting, looseness or mechanical damage.
