Why Choose the ABB 1SAZ801901R1001 DB65 Single Mounting Kit?
The ABB 1SAZ801901R1001, also known as the DB65, is a dedicated single mounting kit for ABB TF65 thermal overload relays. It enables a compatible TF65 overload relay to be installed separately from a contactor, providing greater flexibility when designing motor protection circuits, control panels and industrial machinery.
The DB65 provides the main-circuit connections required when a TF65 overload relay is used as a standalone device rather than mounted directly beneath a compatible ABB contactor. Its robust three-pole construction supports industrial motor circuits with a rated operational current of up to 67 A and a rated operational voltage of up to 690 V AC.
Designed specifically for the ABB TF65 thermal overload relay series, the DB65 features screw connections and accommodates a broad range of conductor sizes. Its compact 55 mm-wide construction makes it suitable for installation inside motor control centres, machinery cabinets and electrical control panels where separate overload relay mounting is required.

Flexible Separate Mounting for Motor Protection
Thermal overload relays are frequently mounted directly to contactors as part of compact motor starters, but some installations require the overload protection device to be positioned separately. The ABB DB65 provides the necessary mounting and main-circuit connection arrangement for installing a TF65 thermal overload relay independently within the electrical enclosure.
Separate mounting can provide greater freedom when arranging components inside control panels, replacing existing motor protection equipment or designing applications where the contactor and overload relay cannot be installed as a combined assembly. The DB65 maintains robust three-phase connections while allowing the TF65 relay to retain its motor overload protection functionality.
Typical Applications
- Separate mounting of ABB TF65 thermal overload relays.
- Industrial motor control centres.
- Electrical control and distribution panels.
- Pump, fan and compressor motor starters.
- Conveyor and material handling systems.
- Manufacturing and production machinery.
- Motor protection system upgrades and retrofits.
- OEM machinery and industrial automation equipment.
