Overview

EN 175301-803:2006 is a CLC (CENELEC) detail specification for rectangular connectors with flat contacts (0.8 mm thickness) and a non‑detachable locking screw. It standardizes a family of 2‑ or 3‑pole connectors plus a protective earth (PE) contact intended for industrial installations and electrical equipment used in measuring, regulating and control circuits, power supply equipment, fluid/air power systems and similar electronic devices.

Key topics and technical requirements

• Contact construction: flat contacts, thickness 0.8 mm; contact finish options referenced in style designation.
• Contact arrangements: 2 + PE and 3 + PE variants; mating dimensions and insert positions defined for styles A, B and C.
• Termination methods: screw and solder terminations (style‑dependent). Maximum conductor cross sections specified (style A/B up to 1.5 mm²; style C up to 0.75 mm²).
• Mechanical styles & mounting: multiple variants for fixed (K, L, M, S, P) and free connectors (H, R) with detailed mounting dimensions and fixing hole configurations.
• Environmental & electrical performance:
  • Climatic category: specified per EN 60068‑1 (e.g. -25 °C to +125 °C; damp heat conditions noted).
  • Degree of protection: IP65 in mated and locked condition (EN 60529).
  • Clearance & creepage: minimum 3 mm clearance and 3.2 mm creepage; rated impulse withstand voltage 4 kV (pollution degree 3).
  • Voltage proof: 2 kV r.m.s. (contact/contact and contact/test panel) per EN 60512.
  • Current carrying: derating curves and test requirements included (EN 60512 references).
• Marking & materials: manufacturer ID, EN type designation, contact position marking, and polymer identification per EN ISO 1043.
• Quality & testing: defined test schedule, sample sizes and qualification/inspection procedures; assessment levels B and G referenced.

Applications and practical use

• Selection and design of panel‑mount and cable‑outlet rectangular connectors for industrial control cabinets, sensors, actuators, power supplies and pneumatics/hydraulics control equipment.
• Definition of mating dimensions, panel cutouts and mounting details for mechanical and electrical integration.
• Specification for procurement and supplier qualification where connector interchangeability, IP65 sealing, electrical safety (clearance/creepage) and test verification are required.
• Basis for product testing, type approval and conformity assessment under assessed‑quality connector programs.

Who uses this standard

• Electrical and mechanical design engineers, product managers, procurement specialists, connector manufacturers and test laboratories working on industrial control systems and equipment requiring standardized rectangular connectors.
