1SAZ711201R1035 ABB T16-4.2 Thermal Overload Relay 3.1-4.2A

The ABB T16-4.2 (article 1SAZ711201R1035) is a thermal overload relay providing electromechanical protection for motor main circuits. Covering a current setting range of 3.1 to 4.2 A with trip class 10, it guards motors against overload conditions and phase failure. The device connects directly to mini contactors or block contactors, making it a compact and economical protection solution.

Technical specifications:

• Series: T16-4.2
• ABB article number: 1SAZ711201R1035
• EAN: 4013614397929
• Current setting range: 3.1 - 4.2 A
• Trip class: 10
• Trip contact: NC
• Signal contact: NO
• Reset mode: automatic or manual, selectable
• Mounting: direct connection to mini contactors or block contactors
• Mounting kit: single mounting kits available as accessory

Features and benefits:

• Protects motors against overload and phase failure for dependable operation
• Selectable automatic or manual reset gives flexibility to suit the application
• Temperature compensation maintains consistent trip behaviour across varying ambient temperatures
• Trip-free mechanism with STOP function prevents bypassing of the protection during a fault
• Trip indication provides immediate visual confirmation of a tripped condition for faster fault diagnosis

Applications:

• Motor protection in direct-on-line starters built around mini or block contactors
• Industrial control panels requiring compact, economical overload protection
• Machine control circuits where phase failure detection is required
• Small motor drive assemblies where a low current range of 3.1 - 4.2 A is needed
