  万能式断路器又称框架式断路器：能接通、承载以及分断正常电路条件下的电流，也能在规定的非正常电路条件下接通、承载一定时间和分断电流的一种机械开关电器。

    万能式断路器的操作靠手动操作或电动合闸的。主触点闭合后，自由脱扣机构将主触点锁在合闸位置上。过电流脱扣器的线圈和热脱扣器的热元件与主电路串联，铝单板是采用优质铝合金板材为基材，再经过数控折弯等技术成型，表面喷涂装饰性涂料的一种新型幕墙材料。欠电压脱扣器的线圈和电源并联。当电路发生短路或严重过载时，过电流脱扣器的衔铁吸合，使自由脱扣机构动作，主触点断开主电路。当电路过载时，热脱扣器的热元件发热使双金属片上弯曲，推动自由脱扣机构动作。分励脱扣器则作为远距离控制用，实践证明，运用TRIZ理论，可大大加快人们创造发明的进程而且能得到高质量的创新产品。在正常工作时，其线圈是断电的，在需要距离控制时，按下起动按钮，使线圈通电，衔铁带动自由脱扣机构动作，使主触点断开。

    万能式断路器为立体布置形式，触头系统、瞬时过电流脱扣器左右侧板均安装在一块绝缘板上。上部装有灭弧系统，操作机构可装在正前方或右侧面，有“分”、“合”指示及手动断开按钮。其左上方装有分励脱扣器，背部装有与脱扣半轴相连的欠电压脱扣器。速饱和电流互感器或电流电压变换器套在下母线上。欠电压延时装置、热继电器或半导体脱扣器可分别装在下方。

    DW15-2000、3200、4000、6300断路器为立体布置形式，由底架、侧板、横梁组成框架，每相触头系统安装在底架上，上面装灭弧室。操作机构在断路器右前方，通过主轴与触头系统相连。电动操作机构通过方轴与机构连成一体装于断路器下部，作为断路器的贮能或直接闭合之用，贮能后的闭合由释能电磁铁承担。在左侧板上方装有防回跳机构，以防止断路器在断开时弹跳。各种过电流脱扣器按不同要求装在断路器下方，欠电压，分励脱扣器及电动操作控制部分装在左侧，其中欠电压、分励脱扣器通过脱扣器与放大机构相连，以减少断路器的脱扣力。12对辅助触头供用户联接二次回路用，面板上有显示断路器工作位置的指示牌“1”“0”和“贮能”指示，还有供合闸及分闸用的按钮“1”“0”（均按下）。DW15-1000、1600断路器附有正面手动操作手柄；DW15-2500、4000附有检修用的手动操作手柄（均可卸下）。
