Load Isolation Switch

 

LTZGL series load isolation switch is suitable for industrial power distribution equipment with AC 50Hz, rated voltage up to 660V, DC voltage up to 440V, and rated heating current up to 3200A. It is used for infrequently connecting and breaking circuits and electrical isolation. It is widely used in In power distribution systems and automation systems in construction, electric power, petrochemical and other industries.

LTZGL transfer load isolating switch is composed of two TZGL load isolating switches stacked up and down or side by side. It is suitable for the switching of two-way power supply or the switching and safety isolation of two load equipment.

The switch complies with IEC60947-3 and GB14048.3 standards.

The switch is beautiful in shape, novel and simple, small in size and full in function, which is the best choice for similar products.

 

 

 

 

Features

 

● The switch adopts modular design and is suitable for making and breaking circuits or electrical isolation. Above 1000A is only used for electrical isolation.

● The switch adopts spring energy storage, instantaneous release acceleration closing mechanism and parallel double-break contact structure for simultaneous connection and disconnection, which greatly improves the electrical and mechanical properties of the product.

● The switch adopts glass fiber reinforced unsaturated polyester molding compound and manual operation handle, which has high dielectric performance, protection ability and reliable operation safety.

● The switch has 3 poles and 4 poles (3 poles + switchable neutral pole).

● There is a marked window on the front of the switch to indicate the on-off state of the contact, and an observation window on the back can be provided as required to directly observe the on-off state of the contact to ensure the reliability and safety of the switch operation.

● The handle can be directly installed on the switch for operation (referred to as operation inside the cabinet), and it can also be operated outside the door of the power distribution cabinet through the extension shaft (referred to as operation outside the cabinet), which provides convenient operation.

● Can provide normally open and normally closed auxiliary contacts and special bottom plate for installation and front-panel and rear-panel wiring according to needs, so as to meet various needs of customers.

● When the breaking position is “0”, the handle can be locked with two to three locks to prevent misoperation.
