FH41LA is a high-performance magnetic retention relay engineered for smart meters, featuring a 100A high current switching capacity and low power consumption, making it appropriate for industrial and electric power applications with stringent reliability demands. The product possesses ISO9001 and ISO14001 certifications and complies with RoHS standards. It is offered in single and twin coil designs and accommodates bespoke accessories (e.g., manganese-copper shunts, transformers, etc.) to fulfill varied requirements.
Magnetic retention design, only consumes power when switching state, no need to supply power in normal state, significantly reducing energy consumption.
Single coil/dual coil options for different control logic (e.g. pulse trigger or continuous signal).
100A resistive load switching capability, maximum switching voltage 250VAC, to meet the needs of high current applications.
Contacts are made of AgSnO₂ material, with contact resistance ≤ 1.0mΩ, durable and excellent conductivity.
High temperature (-40℃~85℃), shockproof (100g impact resistance), dustproof design, adapt to harsh environments.
Electrical life of 100,000 times (mechanical life of 1 million times), to ensure long-term stable operation.
Compact size (34.8×28×16mm), supports PCB mounting or screw fixing, compatible with automated production.
Standard polarity or reverse polarity (optional), flexible wiring.
Smart meter: precise control of power flow and disconnection, support for remote meter reading system.
Industrial control: High-efficiency switching of automation equipment and power management modules.
New energy field: circuit protection of solar inverter and energy storage system.
Precautions for use
Before installation, you need to check the contact status (default closed, transportation may affect), and reset manually if necessary.
Driving voltage is recommended to be 1~1.5 times of rated voltage, pulse width ≥50ms, avoid long time coil energization.
Reflow soldering is prohibited for load terminals, spot welding process is recommended to prevent mechanical stress damage.
Support personalized configuration (e.g. contact form, coil type, accessories, etc.), provide technical consultation and after-sales support.
Choose FH41LA to give your equipment an efficient, durable and energy-saving power control solution!
