Inrush Current Limiters (or ICL for short) play an important role in regulating the amount of current that flows into an electrical system. A quality ICL product should be able to detect inrush currents and limit them to a preset level, thus avoiding any equipment damage and power system disruptions. The SL12 10004-A is a type of ICL product developed by Schneider Electric that is designed to help provide reliable protection against inrush currents.

The SL12 10004-A is a solid-state, bi-directional inrush current limiter with multi-range current control. It is rated at 1000 Amps continuous and 600 V AC, and is designed to protect power circuits from inrush currents. It features an integrated thermostat and a built-in thermal fuse that offers additional protection from surges. This inrush current limiter also has various models for different types of applications and operating conditions, making it suitable for a wide range of applications.

The main purpose of the SL12 10004-A is to protect sensitive electronic equipment from sudden surges of current caused by switching operations of motors, transformers and power supplies. It ensures a reliable protection even for applications with changing inrush current levels such as sinusoidal inrush currents. In addition to its surge protection feature, the SL12 10004-A also offers long-term protection against inrush currents due to its fast response time.

The working principle behind the SL12 10004-A involves a sensing mechanism that is used to detect the inrush current. When inrush currents are detected, the ICL unit activates a circuit that limits the current to the preset level. This is achieved by clamping the current waveform at the upper limit that is set. The SL12 10004-A features adjustable time delays and current limits to enable its adaptability to different system requirements.

As a bi-directional ICL, the SL12 10004-A is capable of reducing both positive and negative inrush currents to the preset level. It is also designed to withstand a wide range of temperature conditions, making it suitable for both indoor and outdoor applications. In terms of environmental protection, it meets the requirements of EN 60204-1, UL and CE standards for hazardous environmental conditions.

The SL12 10004-A is suitable for a wide range of applications, including electric motors, power supplies, drives and transformers. It is also suitable for installations in hazardous locations since it is rated for both indoor and outdoor applications. In addition, it is compatible with a variety of equipment, from dc motors and automated ECUs to transformers and capacitors.

The SL12 10004-A also features a variety of benefits that include reliable performance, easy installation, adjustable current limits, long-term protection and compatibility with a wide range of equipment. With its strong protection and reliable performance, this inrush current limiter is the ideal solution for applications in hazardous settings.
