DW45 Series Split (Closed) Release (Intermittent) Retarders

I. Product Overview Product Overview

DW45 Series Shunt (Closing) Release Coil It is designed for intermittent duty and is suitable for applications requiring momentary energization.

The DW45 series of shunt (closed) release switches are designed for instantaneous operation and are suitable for use in applications where power is applied instantaneously.

Instructions for use: Shunt (closing) Upon access Control loop At that time, it is not allowed. Prolonged connection, Therefore, an auxiliary circuit must be connected to control the product’s energization time. ≤100ms。

Usage method: When connecting to the control circuit, it is not allowed to be left on for a long time. Therefore, an auxiliary must be connected to achieve a power-on time of ≤100 ms for the controlled product.

II. Main Static Characteristics Static main features

2. Maximum tripping force: ≥ 20N。 Maximum disengagement force: ≥20N.

3. Tripping stroke: 7.5 ± 0.5 mm 。 Release stroke: 7.5±0.5 mm.

4. Input instantaneous current: ≤5 A @220V。 Input terminal instantaneous current: ≤5A@220V.

5. This product can withstand 1 Ten thousand times @80° Strengthening test. This product can withstand 10,000 @80° intensive tests.

III. Dynamic Characteristics dynamic characteristics

1. Shunt (intermittent) products, when the input voltage Once the Ue exceeds 70%, the circuit breaker can be reliably closed and opened.

1. The incentive (interruptible) product can reliably close and open the circuit breaker when the input voltage is ≥ 70% of the rated voltage Ue.

2. Closed (intermittent) product, when the input voltage Once the Ue reaches or exceeds 85%, the circuit breaker can be reliably closed.

2. For closed (interruptible) products, the circuit breaker can be reliably closed when the input voltage is ≥ 85% Ue.
