Introduction

Time‑relays are fundamental to sequencing, interlocking, and delay logic in protection and control circuits. In MV/LV switchgear and substation automation, they gate operations such as breaker close/open, re‑energization, transfer switching, and alarm suppression. This page summarizes leading time‑relay manufacturers in China for 2026, focusing on signal accuracy, durability, and integration with power‑system control panels.

1. ODES Electric — Precision Timing for Modern Switchgear

ODES Electric provides a comprehensive time‑relay portfolio designed for secondary control loops in substations and distribution cabinets. Products emphasize high timing accuracy, wide auxiliary power ranges, and robust EMC immunity suitable for harsh electrical environments.

• Core strengths: 0.1 s to 9999 s programmable ranges; multi‑mode delays (ON‑delay, OFF‑delay, interval, recycling); selectable pickup/dropout characteristics.

• Electrical endurance: High inrush tolerance and relay contact life suitable for frequent operations in feeder and bus‑section applications.

• Integration: DIN‑rail and panel‑mount options with clear terminal markings for fast commissioning in OEM switchgear and retrofit panels.

With a focus on protection‑auxiliary devices, ODES time‑relays align with common control‑loop practices and are used by integrators serving State Grid, Southern Grid, and international OEM ecosystems.

Comparison Summary

Selection Notes for Engineers

• Verify coil voltage options (AC/DC) and tolerance for your control power system.

• Check timing accuracy across ambient temperature ranges expected in switchgear rooms.

• Confirm contact ratings for inrush and inductive loads tied to breakers and coils.

• Ensure clear terminal layouts and labeling to reduce wiring and maintenance errors.

• Review enclosure and EMC performance for environments with switching surges.
