Ziehl TR440 Transformer Protection Relay Temperature

Typical applications for the TR440 include signal isolation on instrumentation loops, PLC I/O interfacing, and motor starter circuits within metal processing systems.

Ziehl builds the TR440 to industrial standards that support reliable switching, signaling, or connection performance over long duty cycles.

Part number TR440 uses a letter-based series code common to Ziehl components, where the leading 'TR' characters classify this unit within the broader relay catalog. As a manufacturer active in industrial supply chains, Ziehl produces relay hardware engineered for long service intervals and straightforward maintenance.

For exact dimensions, tolerances, and ratings of the TR440, confirm specifications directly with the Ziehl technical team or request a datasheet through Verkopershulp.nl.

Through Verkopershulp.nl, the TR440 is available alongside the wider Ziehl relay catalog, with consolidated shipping for multi-item orders.

When integrating the TR440 into existing assemblies, verify mechanical envelope, fastening pattern, and connection interface against the Ziehl reference drawing.

The TR440 is commonly specified alongside complementary Ziehl components to maintain a coherent supply chain and simplified spare-parts inventory.
