Why Choose the ABB 1SAZ701901R0001 DB16 Single Mounting Kit?
The ABB 1SAZ701901R0001, also designated the DB16, is a compact single mounting kit for ABB T16 thermal overload relays. It allows a compatible overload relay to be installed independently without connecting it directly beneath a contactor.
By providing the necessary mounting and main-circuit connections, the DB16 supports stand-alone overload protection arrangements in industrial control panels and motor-control systems. The assembled unit can be secured to a standard DIN rail or directly onto a mounting plate, giving panel builders greater flexibility when arranging control equipment.
The ABB DB16 provides a three-pole main circuit with a rated operational current of 16 A and a rated operational voltage of 690 V AC. Its IP20 construction and compact dimensions make it suitable for protected electrical enclosures where a T16 relay must be mounted separately from its associated contactor.
Key Advantages
- Enables stand-alone installation of ABB T16 thermal overload relays.
- Supports mounting without attaching the overload relay directly to a contactor.
- Suitable for installation on a DIN rail or mounting plate.
- Three-pole, 16 A main-circuit design.
- 690 V AC rated operational voltage for industrial motor circuits.
- Compact format supports space-efficient control-panel construction.
Key Features
- ABB DB16 single mounting kit.
- Designed specifically for ABB T16 thermal overload relays.
- Three main-circuit poles.
- 16 A rated operational current.
- 690 V AC rated operational and insulation voltage.
- 6 kV rated impulse withstand voltage.
- IP20 protection when installed correctly.
- DIN rail or mounting-plate installation.
Flexible Stand-Alone Overload Relay Installation
Thermal overload relays are commonly mounted directly beneath compatible contactors as part of a motor starter. Where the control-panel layout or circuit design requires the overload relay to be positioned separately, a single mounting kit provides the main-circuit terminals and mechanical support required for independent installation.
The ABB DB16 allows a T16 thermal overload relay to retain its motor-protection function while being mounted away from the contactor. This provides greater flexibility when designing new panels, modifying existing installations or replacing equipment where direct contactor mounting is impractical.
Typical Applications
- Stand-alone mounting of ABB T16 overload relays.
- Industrial motor-control panels.
- Separate contactor and overload relay arrangements.
- Machinery and production-line control systems.
- Pump, fan and conveyor motor starters.
- Control-panel upgrades and replacement installations.
