Overview
IEC 61076-8-112:2025 is an IEC international standard that defines product requirements for 2‑pole snap‑locking rectangular power connectors with IP65/IP67 plastic housings rated for 50 A. The standard covers overall and interface dimensions, technical characteristics, performance requirements, and test methods. It is intended for connectors with breaking capacity (CBC) per IEC 61984, primarily used for DC power conduction in electrical and electronic equipment.
Key topics
- Scope and object: Detail specification for 2‑pole snap‑locking rectangular power connectors, IP65/IP67, 50 A rated current.
- Dimensions and interfaces: Overall and mating dimensions, fixed and free connector geometries, accessories and mounting information.
- Ratings & characteristics: Rated current, climatic category, clearance and creepage distances, voltage proof, contact resistance, insulation resistance, temperature rise, and current‑carrying capacity.
- Mechanical requirements: Engaging/separating forces, mechanical operation, contact retention, conductor secureness, vibration and shock resistance.
- Breaking capacity (CBC): Requirements and test methods for engaging/separating under electrical load according to IEC 61984.
- Environmental and IP requirements: IP65/IP67 degree of protection, climatic tests (damp heat, temperature cycling, salt mist, dry heat, cold), and relevant material marking.
- Tests and test schedules: Basic and full test schedules, pre‑conditioning, wiring/mounting of test specimens, dynamic stress tests, and measurements (see Test groups P, AP, BP, … KP).
- Normative references: Includes IEC 61984 and other referenced documents needed for correct application.
Applications and who uses it
This standard is relevant to manufacturers, product designers, test laboratories, certification bodies, procurement teams, and systems integrators involved with:
- DC power interconnections in electrical and electronic equipment
- Battery and energy storage interfaces
- Industrial power modules and machinery
- Outdoor or harsh‑environment power connections requiring IP65/IP67 ingress protection
Use of IEC 61076-8-112:2025 helps ensure dimensional compatibility, electrical safety, mechanical reliability and environmental robustness for 50 A 2‑pole power connector solutions.
