FAQs
The 1533 supports back-wire termination and traditional screw connections, accommodating up to three wires in a two-pole, three-wire receptacle with grounding. This dual termination capability speeds up field installation and simplifies retrofits on existing panels while maintaining a secure, durable connection.
Yes. The 1533 is designed for a two-pole, three-wire configuration with grounding and is compatible with standard NEMA 5-20R configurations, ensuring straightforward integration with common 20A, 125V circuits in industrial equipment.
The connector uses nickel-plated brass contacts with a thermoplastic body and nylon face, delivering corrosion resistance and robust mechanical performance in corrosive environments, washdowns, and harsh municipal or manufacturing settings.
The 1533 is cULus Listed, indicating safety certification for the US and Canada, with UL/CSA recognition implied by the listing. This supports regulatory compliance in North American facilities and aids in supplier qualification and audits.
Field reliability improves due to corrosion-resistant materials and secure terminations, reducing downtime and maintenance visits. The combination of easy back-wire or screw terminations, standard cord compatibility, and a core-pack packaging approach also lowers inventory waste and procurement complexity, contributing to lower total cost of ownership over the equipment lifecycle.
