What is the function of an undervoltage release accessory?
An undervoltage release accessory is designed to trip a circuit breaker automatically when the voltage drops below a preset level. This ensures protection against voltage dips that could potentially cause harm to electrical equipment or create unsafe operating conditions.
Can this undervoltage release be used with any circuit breaker?
No, this specific undervoltage release is compatible with Siemens 3VA1 and 3VA20 up to 3VA25 circuit breakers. It is important to match the accessory to the correct breaker model for proper operation.
What voltage is required for this undervoltage release to operate?
This undervoltage release operates with a control supply voltage of 24 V DC, which is the standard voltage required for it to function correctly.
What are the dimensions of this undervoltage release accessory?
The dimensions of the undervoltage release are 25.7 mm in width, 28.6 mm in depth, and 65.1 mm in height, making it compact and suitable for integration with compatible circuit breakers.
How is the undervoltage release accessory installed?
The undervoltage release accessory is installed internally in the circuit breaker, typically by clipping or securing it into a designated slot within the breaker. Installation should be carried out by a qualified electrician to ensure safety and proper operation.
What is the degree of pollution for this undervoltage release?
The undervoltage release is rated with a degree of pollution of 3, which indicates that it is designed to operate in environments where conductive pollution or dry non-conductive pollution occurs that becomes conductive due to condensation.
What is the overvoltage category for this accessory?
The undervoltage release accessory falls under overvoltage category III, which means it is suitable for use in equipment in fixed installations and similar applications.
Is there a specific torque requirement for the terminal connections?
Yes, the terminal connections have a recommended torque of 0.4 N·m and a maximum torque of 0.5 N·m. It is important to adhere to these specifications to ensure a secure and reliable connection.
What is the consumed active power of this undervoltage release?
The consumed active power of the undervoltage release at maximum is 2.5 W when operating at its designated DC voltage.
What is the surge voltage resistance of this accessory?
The undervoltage release has a surge voltage resistance of 4 kV, providing robust protection against transient voltage spikes.
