Product catalog summary

Overview: The document provides technical specifications and operational guidelines for the DWB02 and PWB02 power monitoring relays, designed for monitoring active power in three-phase networks with symmetrical loads. These devices are used to oversee the load of asynchronous motors and other symmetrical consumers.

Specifications:

Active power monitoring with separate upper and lower threshold settings on an absolute scale.
Voltage measurement of the power supply and true RMS measurement.
Current measurement options include direct connection or current transformer connection.
Adjustable start-up delay from 1 to 30 seconds using a rotary knob.
Programmable self-holding or blocking of the output at set thresholds.
Automatic and manual load switching capabilities.
Output: Single-pole changeover relay, 8 A, selectable energized or de-energized in the resting state.
Mounting options: DIN rail (DWB02) or plug-in module (PWB02).
LED indicators for relay status, alarm, and operating voltage.

Technical Data:

Input voltage ranges: 208 to 240 VAC, 380 to 480 VAC, and 600 to 690 VAC, with ±15% tolerance.
Current ranges: Direct input from 0.5 to 10 A, with maximum currents of 30 A and 50 A respectively.
Standard current transformers available for higher current ranges.
Operating temperature: -20 to 60°C at 50 Hz, -20 to 50°C at 60 Hz.
Protection class: IP 20, with pollution degree 3 for DWB02 and 2 for PWB02.
Mechanical and electrical endurance: ≥ 30 million and ≥ 100,000 operations respectively.

Functionality:

The relays measure active power in three-phase networks and can prevent motor overload during startup by adjusting the relay's start-up delay.
Self-holding and blocking functions are available, with LED indicators signaling alarm situations and relay status.
Various operational modes can be set using DIP switches, including self-holding, blocking, and start/stop functions.

Installation and Operation:

Relays can be connected directly to motors or through current transformers.
Settings for function, range, thresholds, and time delays are adjustable via DIP switches and rotary knobs.
Specific examples illustrate different operational scenarios, such as self-holding relays and start/stop mode.

Compliance and Standards:

Complies with UL, CSA, and CE standards.
EMC immunity and emission standards according to DIN EN 61000-6-2 and DIN EN 50081-1.
