Mean Well ICL-28R inschakelstroombegrenzer-module, 28 A, DIN-rail, grijs

Industrial control panel builders and machine integrators use the Mean Well ICL-28R to protect upstream circuit breakers and relays from the high inrush currents drawn by capacitive loads such as LED drivers, switch-mode power supplies, and motor drives. Mounted on a standard DIN rail, this grey module limits peak current to 40 A and then bypasses its NTC thermistor after 100 ms, allowing full current flow with minimal losses.

Key specifications

• Input voltage range: 180 – 264 VAC
• Max continuous current: 28 A
• Peak inrush current limiting: 40 A
• Bypass time: 100 ms
• Operating temperature: -30 to +70 °C
• Mounting: DIN rail
• Protection: internal bypass relay, NTC thermistor
• No-load power consumption: <1 W
• Dielectric strength: 3 kVAC (input to output)
• Insulation resistance: >100 MΩ at 500 VDC
• Humidity: 20 – 90% RH non-condensing
• Housing material: plastic, grey
• Certifications: UL, cUL, TUV, CE
• Application: inductive and capacitive loads
• Series: ICL-28R/L

Why choose it

The ICL-28R combines a robust NTC thermistor with an internal bypass relay, ensuring that after the initial current surge is suppressed, the thermistor is shorted out to reduce power loss and heat generation. This design supports high continuous currents up to 28 A and operates reliably across a wide temperature range, making it suitable for demanding industrial environments.

Ideal use cases

• Limiting inrush current in LED lighting installations
• Protecting relays and circuit breakers in control panels
• Soft-starting switch-mode power supplies and frequency inverters
• Industrial automation systems with capacitive or inductive loads

Good to know

The ICL-28R is part of the ICL-28R/L series and is designed for both inductive and capacitive loads. Its compact DIN-rail housing simplifies installation in distribution boards and machine control cabinets.
