L&T (Larsen & Toubro) offers a wide range of 3-pole switchgear that is designed to meet the needs of industrial, commercial, and residential electrical systems. These switchgears are used to control and protect electrical circuits by enabling or interrupting the flow of current in three-phase systems. Below are the general specifications for L&T 3-pole switchgear, including circuit breakers and contactors:

• Range: Typically from 6A to 1250A, depending on the specific model.
• Capacity: Can handle varying loads, suitable for industrial motors, lighting circuits, and heavy electrical appliances.

• AC Voltage Rating: Generally supports 230V, 415V, and 690V AC, with certain models capable of handling higher voltages.
• DC Voltage Rating: Some models also support DC voltage up to 250V.

• 3-pole configuration, ideal for three-phase power systems.

• Suitable for 50Hz and 60Hz frequency applications.

• Short-circuit breaking capacity: Typically rated at 10kA, 25kA, 50kA, or 70kA, depending on the model and application requirements.
• Rated operational breaking capacity to safely interrupt the circuit under short-circuit conditions.

• Overload Protection: For protecting against prolonged overcurrent conditions.
• Short Circuit Protection: Safeguards the system from short-circuit events.
• Earth Fault Protection: In some models, designed for systems where earth leakage detection is critical.

• NO (Normally Open) / NC (Normally Closed) auxiliary contacts for remote control, signaling, and monitoring.

• DIN Rail Mounting: Easy installation on standard 35mm DIN rails for control panels and distribution boards.
• Panel Mounting: Some models are designed for panel mounting as per installation requirements.

• Coil Voltage Options: Available in a range of coil voltages including 24V, 110V, 230V, and 400V (AC/DC).

• IP Rating: Typically IP20, designed for indoor use in dry conditions. Certain models may offer higher protection (IP40, IP54) for outdoor or harsher environments.

• Operational Temperature Range: Typically from -5°C to +50°C depending on the model.

• IEC 60947-2: Compliant with international standards for circuit breakers.
• IEC 60947-4-1: For contactors and switchgear.
• UL/CSA Certification: Certain models also comply with UL and CSA standards.

• Adjustable overload protection settings for fine-tuning current limits based on system requirements.

• Thermal-magnetic tripping: Combination of thermal protection for overload conditions and magnetic tripping for short-circuit protection.
• Electronic tripping options available for more advanced protection and precision.

Product Details:

The 100 Amp 3-Pole L&T Switchgear is a high-performance electrical device designed for controlling and protecting electrical circuits in three-phase systems. It is ideal for use in a wide range of industrial, commercial, and residential applications, particularly where moderate current control and protection are required, such as for motor control, distribution panels, and lighting circuits.

The switchgear consists of three poles, each responsible for handling one phase of the three-phase system, ensuring reliable power distribution. It is engineered to provide overload protection, short-circuit protection, and safe switching of electrical loads. With a 100A current rating, this switchgear can handle significant power without compromising performance or safety.
