Product News 70

Product catalog summary

Overview: The document provides technical specifications and features of the 70 Series line monitoring relays, specifically designed for three-phase applications. These relays are multifunctional, offering capabilities such as monitoring undervoltage, overvoltage, window mode, phase rotation, phase loss, asymmetry, and neutral loss.

Key Features:

2 CO relay output with 8 A capacity.
Positive safety logic ensuring the output contact opens if an error is detected.
Adjustable functions and values via a front-facing selector and trimmer.
Compatible with both flat blade and cross head screwdrivers for adjustments.
Colored LEDs for immediate visual indication.
Modular housing with a 35 mm width, suitable for 35 mm rail (EN 60715) mounting.

Specifications:

Nominal system voltage for three-phase applications is 380...415 V AC.
Voltage detection level range is 300...480 V.
Contact configuration varies by type, with options for 1 CO (SPDT) and 1 CO (DPDT).
Adjustable trip delay time ranging from 0.5 to 60 seconds.
Dimensions for most models are 35 x 60 mm.

Functions:

Undervoltage and overvoltage monitoring.
Window mode for voltage range monitoring.
Phase loss and phase rotation detection.
Asymmetry and neutral loss detection for specific models.

Phase Failure Relays:

Types 70.61 and 70.62 are designed for three-phase systems with a voltage range of 208...480 V AC.
Fixed trip delay time of 0.5 seconds.
Dimensions vary, with Type 70.61 at 17.5 x 60 mm and Type 70.62 at 22.5 x 100 mm.
