Inrush current limiter 16A ICL-16L

Inrush current limiter – protection and reliability of the installation

The ICL-16L inrush current limiter is a component designed to reduce high surge currents that occur during the start-up of devices with capacitive or inductive loads. The device effectively prevents unnecessary tripping of overcurrent circuit breakers, increasing the reliability of the entire power system. This is particularly important in installations where stability and continuity of operation are crucial.

ICL-16L stands out with a design based on a cement resistor and a bypass relay, which ensures constant effectiveness in limiting the inrush current, unlike solutions using NTC thermistors. Thanks to this, the device does not consume energy during normal operation and does not generate additional heat. Installation is carried out by embedding it in the housing (L version), which allows for discreet integration with the existing electrical infrastructure.

Construction features and application

ICL-16L is designed for mounting inside devices or electrical enclosures. Its compact dimensions allow it to be used even in limited spaces. The device finds application wherever it is necessary to limit surge currents, such as:

• Switching power supplies (SPS) – protection against tripping circuit breakers when starting capacitive loads.
• Lighting installations – protection against current surges when switching on lamps.
• Electric motors – reduction of inrush currents that can damage the electrical installation.
• Industrial automation systems – ensuring a stable power supply for sensitive electronic components.

Advantages and benefits of use

• Effective protection: Limits the inrush current to 16A continuous, protecting overcurrent circuit breakers from unnecessary activation.
• Durable construction: The use of a cement resistor ensures constant effectiveness for a long time.
• No energy loss: The bypass relay minimizes power loss during normal device operation.
• Simple installation: The built-in version (ICL-16L) facilitates integration with existing electrical systems.
• Wide range of input voltages: Support for voltages of 180-264VAC ensures compatibility with various electrical networks.
• Increased reliability: Stable device operation translates into greater reliability of the entire power system.
• Cost savings: Prevents failures and downtime caused by tripping overcurrent circuit breakers, which translates into financial savings.

It is important to choose the correct overcurrent circuit breaker (MCB) to work with ICL-16L – types C or D are recommended to ensure optimal protection of the electrical installation. The selection should take into account the rated current and short-circuit capacity of the circuit breaker, as well as the characteristics of the load.
