Modular isolating switch 1P 32A 230VAC SBN132

Isolator switch – reliable disconnection in the installation

This single-pole isolator switch with a rated current of 32A is a key element of any electrical installation where safe and reliable disconnection of the circuit is required. It will work both in residential and industrial installations, providing effective isolation and the possibility of servicing. Its modular design makes it easy to mount on a DIN rail, and its compact dimensions (only 1 module wide) allow for optimal use of space in the switchboard.

Functionality and application

The SBN132 switch is used as a main switch or individual switch in electrical circuits. It is important to remember that it does not have built-in overcurrent protection – its function is only to disconnect the power supply. The ability to lock in the ON or OFF position with a seal increases safety and prevents accidental switching on or off. This makes it ideal for applications where certainty of circuit status is required, e.g. during maintenance work.

• Application: residential and industrial switchboards, electrical installations
• Function: main switch, individual switch
• Application: safe disconnection of circuits during servicing and maintenance
• Sealable: increased safety and protection against accidental change of state

Technical characteristics and mounting

The switch is characterized by high reliability confirmed by the rated switching capacity of 0.677 kA and electrical endurance at the level of 25000 switching cycles. Mounting on a standard DIN rail is quick and intuitive, and screw terminals provide a solid connection of the wires. The degree of protection IP20 guarantees protection against finger contact, which increases safety. Compact dimensions – width 17.5 mm and depth 68 mm – allow for easy adaptation to existing electrical infrastructure.

The rated current is 32 A, and the rated voltage is 230 V. The device has one pole and a rated switching capacity of 0.677 kA. Its width is only 1 module, and the degree of protection IP20 provides basic protection against contact. The installation depth is 68 mm. Short-circuit strength (Icw) is 0.48 kA, which ensures stable operation of the device even in the event of short-term overloads. The operating temperature range from -40°C to +80°C allows the switch to be used in various environmental conditions.
