TL313 Series Magnetic Holding Relay overview:
The TL313 Series Magnetic Holding Relay is a high-performance switching solution designed for energy-efficient and high-load applications. Featuring 150A switching capacity and 200A continuous current rating, this relay delivers robust performance in compact dimensions (39.4mm×22mm×27.5mm). Its pulse-driven operation ensures zero static power consumption, making it ideal for smart energy systems like prepaid meters and industrial automation.
Key advantages include 4KV insulation between contacts and coil, strong magnetic arc suppression, and compliance with RoHS and IEC62055-31 UC2 standards. Available in single/dual coil configurations with 9V–48V DC options, the TL313 achieves reliable switching via ≥50ms pulses while maintaining a 300,000-cycle mechanical lifespan.
Engineered for harsh environments, it operates at -40°C to +85°C and withstands 100G shock resistance, ensuring stability in power distribution, telecom, and motor control systems. The silver alloy contacts minimize resistance (≤5mΩ) and support up to 37,500VA switching power.
Choose the TL313 magnetic holding relay for applications demanding high reliability, low energy consumption, and long-term durability.
