Overview

IEC 61076-8-111:2025 is an International Standard specifying product requirements for 3‑pole snap‑locking rectangular power connectors with IP65/IP67 plastic housing rated at 20 A. The standard covers overall and interface dimensions, technical characteristics, performance requirements and detailed test methods. It applies to connectors with breaking capacity (CBC) per IEC 61984, primarily used for AC power conduction in electrical and electronic equipment.

Key topics

Mechanical and dimensional requirements
- Overall and interface dimensions for free and fixed connectors, mounting and accessory information, and gauges for sizing and retention.
Electrical characteristics
- Ratings, current‑carrying capacity, contact resistance, insulation resistance, voltage proof, and temperature rise limits.
Safety and materials
- Marking, clearance and creepage distance, classification into climatic categories, and design/use of plastics (insulation material marking).
Performance and reliability
- Mechanical operation, contact retention, engaging/separating forces, effectiveness of coupling devices and breaking capacity (engaging and separating with electrical load).
Environmental & durability tests
- IP degree verification (IP65/IP67), vibration (sine), shock, damp heat, rapid temperature change, salt mist (corrosion), dry heat and cold.
Test schedules and procedures
- Basic (minimum) and full test schedules, pre‑conditioning, wiring/mounting of specimens and measurement methods.

Applications

IEC 61076-8-111:2025 is intended for use where compact, rugged 3‑pole power connections with ingress protection are required, including:

Industrial control and automation modules
Outdoor or enclosure‑mounted equipment requiring IP65/IP67 protection
Machine tools, power distribution modules and small power supplies
OEM component specifications and product families that require consistent mating interfaces

Who benefits:

Connector manufacturers (product design and type approval)
Design engineers (component selection, PCB or panel integration)
Test laboratories & certification bodies (compliance testing to the standard’s test schedules)
Procurement and OEMs (ensuring interchangeability and safety)
Systems integrators (selecting reliable connectors for harsh environments)
