Cross Roller Plunger	10A / 250V	DPDT 1NO 1NC	SCREW TYPE

• Forced open action device (NC contacts only), it can disconnet the contact when the contact has fusing and other failures.
• The set safety of lever ensures that gear ratcheting device is used between the action position indicator panel and the lever.
• Strengthened top seal structure improves the sealing performance.
• Built-in contact holder has fast-action type: 1NC / 1NO; Slow-action: 1NC / 1NO and 2NC.
